一、前言 1973年《铁路标准设计通讯》第5期,发表了“铁路路堑挡土墙简捷设计介绍”一文(以下称“简文”)。对平行四边形重力式俯斜路堑挡土墙的设计,按照“简文”介绍的方法,可以简化设计工作,提高设计速度,因此有研究、使用和推广的价值。但“简文”得出的结论还有些问题。“简文”写道:“重力式挡土墙断面大,抗倾倒的稳定性好。同时山区铁路
I. Preface The fifth edition of “Railway Standard Design and Communication,” 1973, published a paper entitled “Brief Introduction to Design of Railway Crawler Retaining Walls” (hereinafter referred to as “Essay”). The design of parallelogram gravitational undercut retaining wall can simplify the design work and increase the design speed according to the method introduced by “Simple article”, so it has the value of research, use and promotion. However, “Jane Wen” draw conclusions still some problems. “Jane Wen,” wrote: "Gravity retaining wall section, anti-dumping stability is good at the same time mountain railway
